Description

Technical Field

[0001] The invention relates to the technical field of yarn detection, in particular to a tensile force detection device and a detection method used in a yarn production process. Background Art

[0002] Yarn is a textile product processed from various textile fibers into a certain fineness. It is used for weaving, rope making, thread making, knitting and embroidery, etc. It is divided into short-staple yarn, continuous filament, etc. After the yarn is produced, in order to determine its quality, some yarn samples are generally subjected to tensile testing to obtain the tensile strength of the yarn and discover the yarn weaknesses, which is conducive to subsequent improvement and optimization.

[0003] A tensile force detection device for use in a yarn production process is disclosed in a patent application with reference publication number CN113466034A. The detection device can stably and conveniently fix the yarn during a tensile force test through the interaction between a rotating shaft, a rotating wheel, a linkage plate, a convex rod, a movable plate, a fixed plate, a winding rod, a touch rod, and a fixed rod. This avoids the situation in which the operator needs to fix the yarn to the device by tying a knot during the tensile force test, which makes it inconvenient to handle the knotted yarn after the test. This is conducive to the continuous tensile force test of the yarn.

[0004] The above detection device can complete the fixing work of the yarn by cooperating with the fixing plate and the winding rod, which is conducive to the detection work. However, during the winding process of the yarn, the two ends of the yarn need to be respectively wound on the two winding rods, and then the corresponding rotating shafts of the two winding rods are respectively controlled to complete the corresponding fixing work. The overall operation is time-consuming and laborious, and the operator needs to repeatedly fix the two ends of the yarn. At the same time, the two ends of the yarn need to be controlled separately to fix the work, which is not conducive to the efficient performance of the test work;

[0005] At the same time, in the yarn test, it is often necessary to test the yarn multiple times to ensure the accuracy of the test and avoid accidental conditions. The above-mentioned detection device requires the operator to repeatedly install and disassemble the two ends of the yarn during the repeated testing of the yarn, which increases the test workload and makes it impossible to complete repeated tests on the yarn continuously and quickly, which affects the timeliness of the test work and results in low test efficiency.

[0048] It is worth noting that: when conducting the test: by providing a test mechanism, the yarn body 4 is pulled to the clamping interval of the two clamping members 5, and then the synchronization mechanism is started, the No. 2 power member 16 is started, and the push arm 15 is pushed forward under the guidance of the two No. 2 rails 14, and the No. 1 arm 19 and the No. 2 arm 20 are pushed forward synchronously through the push arm 15, and the movable clamping blocks 53 on the two clamping members 5 are synchronously driven to move toward the fixed clamping block 52 to complete the clamping restriction of the yarn body 4, thereby completing the synchronous fixation of the two ends of the yarn body 4, reducing the clamping process of the yarn body 4, and after the yarn body 4 is clamped, it is only necessary to start the No. 1 power member 6, and pull the clamping member 5 slidingly set on the two No. 1 rails 7 to move synchronously, and the tension data is collected in real time through the force sensor 8, and transmitted to the upper computer to complete storage and display work, until the yarn body 4 breaks, so as to obtain the ultimate strength of the structure of the yarn body 4, and then the No. 2 power member 16 pulls the push arm 15 to reset, so that the two movable clamping blocks 53 are separated from the fixed clamping block 52 to complete the unlocking;

[0049] A synchronization mechanism is installed in combination on the test mechanism, and the synchronization mechanism completes synchronization control with the test mechanism, and the two clamping members 5 are synchronously driven by the synchronization mechanism to complete the restriction and release action of the yarn body 4, and a guiding mechanism is added on one side of the test table 1, and the guiding mechanism is used to complete the conveying and guiding work of the yarn body 4, and a reciprocating mechanism is added on the test table 1, and the reciprocating mechanism can complete the restriction and release action of the yarn body 4, and the reciprocating mechanism is coordinated with the test mechanism.

An absolute encoder is installed on the drive motor 36, and the absolute encoder is used to accurately position the drive motor 36.

[0052] Embodiment 2: Based on the synchronization mechanism provided in Embodiment 1, this embodiment provides a further technical solution of the synchronization mechanism.

[0053] like Figure 3 , Figure 5 and Figures 10 to 12 As shown, the synchronization mechanism includes two No. 2 rails 14 symmetrically mounted on the test bench 1, and the two No. 2 rails 14 are hidden in the test bench 1. A space allowing the synchronization mechanism to be stored is provided in the test bench 1. A push arm 15 is slidably engaged with the two No. 2 rails 14, and a No. 2 power member 16 is provided on the test bench 1. The No. 2 power member 16 specifically adopts a cylinder, an electric cylinder and an electric linear module to complete the forward and backward pushing work. The output end of the No. 2 power member 16 is detachably fixedly connected to the middle position of the back of the push arm 15, a slideway 17 is provided on the front end surface of the push arm 15, and a slide 18 is slidably engaged in the slideway 17. An arm No. 19 is detachably fixedly installed on one side of the front end surface of the push arm 15, and the arm No. 19 is detachably fixedly connected to a movable clamp 53 on a side away from the No. 1 power member 6, and a No. 2 arm 20 is detachably fixedly installed on the front end surface of the slide 18, and the arm No. 2 arm 20 is detachably fixedly connected to the movable clamp 53 on a side close to the No. 1 power member 6;

[0054] It is worth noting that when the yarn body 4 is clamped and released, the two movable clamps 53 can be synchronously driven by the second power member 16 to clamp and unlock the yarn body 4. At the same time, during the test, the slide 17 and the slide 18 cooperate to follow the movement amount during the test, so that the pressing member 5 can stably slide to test the yarn body 4.

[0055] In the embodiment of the present invention, an air chamber 21 is hidden in the concave sliding seat 51 of the two clamping members 5. The air chamber 21 is open toward the fixed clamp block 52. A push rod 22 is slidably and sealedly penetrated on the side of the air chamber 21 away from the fixed clamp block 52. A switching head 23 is arranged in the air chamber 21. The switching head 23 moves in the air chamber 21 to complete the switching air supply action. When the switching head 23 follows the movable clamp block 53 and moves away from the fixed clamp block 52, the switching head 23 completes the air supply to the second air nozzle 26. The switching head 23 is detachably fixedly connected to the push rod 22 in the air chamber 21, and the push rods 22 on the two clamping members 5 are respectively connected to the first arm 19 and the second arm 2 0 is detachably fixedly connected, and three No. 2 air pipes 24 are respectively connected and installed on the side of the air chamber 21 away from the fixed clamp block 52, and No. 2 manual valves for controlling the on and off of the three No. 2 air pipes 24 are installed at the ends of the three No. 2 air pipes 24, and a spray chamber 25 is installed on the top of the air chamber 21 through a bracket, and a plurality of No. 2 air nozzles 26 are evenly connected and distributed on the top of the spray chamber 25, and the plurality of No. 2 air nozzles 26 are correspondingly covered and arranged on the clamping space of the fixed clamp block 52 and the movable clamp block 53 for the yarn body 4, and the spray chamber 25 is connected to one of the No. 2 air pipes 24 through a spring tube, and the No. 1 air pipes 13 of the fixed clamp block 52 and the movable clamp block 53 are respectively connected to the other two No. 2 air pipes 24 through spring tubes;

[0056] It is worth noting that: at the same time, when the second power member 16 is linked with the movable clamping block 53 to move forward, the friction ring 231 of the switching head 23 is in friction contact with the air chamber 21 to complete the restriction. Therefore, during the forward movement, the push rod 22 acts on the circular plate 232, so that the switching rod 234 pushes the blocking plate 233 away from the friction ring 231, and compresses the reset spring 235. Under the restriction of the reset spring 235, the gas is communicated through the hollow structure of the friction ring 231, that is, no work is done, so as to avoid the ejected gas from interfering with the clamping work of the yarn body 4;

[0057] When the push arm 15 pulls the movable clamp block 53 and the fixed clamp block 52 away from the reset path, under this path, the friction ring 231 continues to rub against the air chamber 21, and the push arm 15 drives the blocking plate 233 to contact with the friction ring 231 to complete the seal, and completes the restriction of the friction ring 231 through the reset spring 235, so that the friction ring 231 and the blocking plate 233 are in stable contact. At this time, the push rod 22 completes the pulling of the switching head 23, driving the switching head 23 to complete the piston movement in the air chamber 21, that is, squeezing and discharging the gas at the front end of the air chamber 21, and delivering the gas to the spray chamber 25 through the No. 2 air pipe 24, and passing through the No. The gas nozzle 26 sprays out to complete auxiliary cleaning of the residual yarn body 4 on the pressing member 5. At the same time, the gas can also be sent into the cavity 9 through the No. 2 gas pipe 24 and the No. 1 gas pipe 13, and sprayed out through the No. 1 gas nozzle 11 on the fixed clamp block 52 and the No. 2 clamp block 39, and the gas is guided and discharged through the through-hole area 12 to complete auxiliary cleaning of the residual yarn body 4 on the fixed clamp block 52 and the movable clamp block 53. The three No. 2 gas pipes 24 can be freely controlled to open and close. The operator can freely switch to open and close the three No. 2 gas pipes 24 according to the needs in the actual working environment, so as to obtain different auxiliary cleaning actions;

[0058] In the embodiment of the present invention, the switching head 23 includes a friction ring 231, which is hollow and in sliding and sealing contact with the air chamber 21. A circular plate 232 is concentrically mounted on the top of the friction ring 231, and a plurality of air holes are formed through the circular plate 232. The plurality of air holes are used to guide the gas flowing through the hollow area of ​​the friction ring 231 during the forward movement of the switching head 23. The circular plate 232 is detachably fixedly connected to the push rod 22. A blocking plate 233 is concentrically mounted below the friction ring 231. The blocking plate 233 is used to guide the friction ring 231. To complete the blocking, a switching rod 234 is installed between the circular plate 232 and the blocking plate 233. The diameter of the switching rod 234 is smaller than the hollow area of ​​the friction ring 231, that is, the switching rod 234 will not cause any obstruction to the friction ring 231, and a return spring 235 is sleeved on the outside of the switching rod 234. The return spring 235 is set between the circular plate 232 and the friction ring 231. The return spring 235 pushes the friction ring 231 toward the blocking plate 233 to complete the blocking, and the elastic coefficient of the return spring 235 is smaller than the friction force between the friction ring 231 and the air chamber 21.

[0059] Embodiment 3: Based on the reciprocating mechanism provided in Embodiment 1, this embodiment provides a further technical solution of the reciprocating mechanism.

[0060] like Figures 13 to 15As shown, the reciprocating mechanism includes a swing arm 35 rotatably installed on the test bench 1 through a pin shaft, and the swing arm 35 is an L-shaped structure as a whole. A drive motor 36 is installed through a bracket above the No. 2 power member 16 in the test bench 1. The output end of the drive motor 36 is transmission-connected with the swing arm 35, and the swing arm 35 is driven by the drive motor 36 to swing back and forth to complete the feeding action of the yarn body 4. An adjustment area 37 is provided through the front end of the swing arm 35 away from the drive motor 36, and a No. 1 clamp block 38 is detachably fixedly installed at the bottom of the front end of the swing arm 35, and a No. 2 clamp block 39 is slidably engaged in the adjustment area 37. The No. 1 clamp block 38 and the No. 2 clamp block 39 are distributed in parallel, and the No. 1 clamp block 38 and the No. 2 clamp block 39 are respectively matched with the limiting positions of the yarn body 4 on the guide mechanism and the test mechanism, so that the reciprocating mechanism can complete the feeding action of the yarn body 4 through the No. 1 clamp block 38 and the No. 2 clamp block 39. For the reciprocating conveying of the yarn body 4, a power part No. 3 40 is installed on the side away from the clamping block No. 1 38 in the adjusting area 37. The power part No. 3 40 specifically adopts a cylinder, an electric cylinder and an electric linear module to complete the forward and backward pushing work. The output end of the power part No. 3 40 is connected to the back of the clamping block No. 2 39 by transmission. The clamping block No. 2 39 is pushed toward the clamping block No. 1 38 by the power part No. 3 40 to complete the clamping work. Limiting parts are detachably installed on both sides of the two clamping parts 5 on the front end surface of the test bench 1. The two limiting parts are used to limit the extreme swinging position of the swing arm 35, and the limiting part position of the clamping part 5 close to the sliding side is lower than the position of the clamping part 5 close to the fixed side, so that the swing arm 35 can carry the yarn body 4 to move to the clamping part 5 on the sliding side, which is beneficial to the conveying of the yarn body 4, and the specific positions of the two limiting parts can be freely adjusted according to the processing conditions;

[0061] It is worth noting that when the yarn body 4 is reciprocated and loaded, the reciprocating mechanism is provided. Under normal circumstances, the bobbin is inserted into the insertion rod 28 to complete the restriction, and then the yarn body 4 passes through the No. 1 guide wheel 30 and the No. 2 guide wheel 33 to complete the rotation guidance. The subsequent yarn body 4 is restricted on the two clamping members 5. Under the action of the limiting spring 34, the No. 2 guide wheel 33 is pushed to carry a certain pressure to contact the No. 1 guide wheel 30, so that the No. 1 guide wheel 30 and the No. 2 guide wheel 33 can complete the restriction of the yarn body 4. At this time, the swing arm 35 is close to the guiding mechanism, and the No. 1 clamp block 38 and the No. 2 clamp block 39 thereon are close to the yarn body 4. At this time, it is only necessary to start the No. 3 power member 40 to push the No. 2 clamp block 39 to move toward the No. 1 clamp block 38 to complete the clamping and fixing of the yarn body 4, which is conducive to the subsequent traction and transportation of the yarn body 4.

[0062] When the second clamp block 39 moves toward the first clamp block 38, the linkage rack 41 moves synchronously. Since the rack 41 is in contact with the first gear 44, the rack 41 moves forward, and the first gear 44 and the first arc-shaped member 42 are synchronously linked to rotate. Under this action, since the second gear 45 is meshed with the first gear 44, the second arc-shaped member 43 is synchronously linked to rotate, so that the first arc-shaped member 42 and the second arc-shaped member 43 move closer to each other to complete the closing, and the open area 2 on the first arc-shaped member 42 can complete the storage of the second arc-shaped member 43. Therefore, the closing of the first and second arc-shaped members 42 and 43 can complete the additional restriction of the yarn body 4, and at the same time, the yarn body 4 can be moved, so that the yarn body 4 is restricted between the first and second arc-shaped members 42 and 43, thereby ensuring the stability of the yarn body 4 and facilitating the first and second clamp blocks 38 and 39 to complete the clamping of the yarn body 4;

[0063] Subsequently, it is only necessary to start the driving motor 36 to drive the swing arm 35 to complete the swinging. At this time, the yarn body 4 is restricted by the No. 1 clamping block 38 and the No. 2 clamping block 39, so that the yarn body 4 follows the swing arm 35 to be pulled to the side of the two clamping members 5, so that the yarn body 4 is pulled and transported to the clamping area of ​​the two clamping members 5. At this time, the synchronization mechanism acts to complete the clamping and fixing of the yarn body 4, and then the No. 3 power member 40 is reset to complete the release of the yarn body 4. Subsequently, the swing arm 35 is reset to the side of the guide mechanism to complete the clamping action of the yarn body 4 again, and then the testing mechanism performs the testing work. Repeating the above actions can complete the continuous traction and transportation work of the yarn body 4, saving time and effort, and being able to complete multiple repeated testing work on the yarn body 4, thereby improving the testing accuracy.

[0064] In the embodiment of the present invention, two racks 41 are symmetrically slidably engaged on both sides of the swing arm 35, and the tails of the two racks 41 are detachably fixedly connected to the second clamp block 39, and a limiting seat cooperating with the two racks 41 is provided on the swing arm 35, and the sliding guidance of the racks 41 is completed by the limiting seat, and two No. 1 arc-shaped parts 42 are symmetrically rotatably installed on both sides of the front end of the swing arm 35 near the No. 1 clamp block 38, and two No. 2 arc-shaped parts 43 are symmetrically rotatably installed on one side of the two No. 1 arc-shaped parts 42 at the front end of the swing arm 35, and a No. 1 gear 44 is fixedly sleeved on the outside of the two No. 1 arc-shaped parts 42 near one side of the swing arm 35, and the No. 1 gear 44 is meshed with the rack 41, and the two No. 1 arc-shaped parts 43 are symmetrically rotatably installed on both sides of the two No. 1 arc-shaped parts 42. A No. 2 gear 45 is fixedly sleeved on the outer side of each No. 2 arc-shaped member 43 near the swing arm 35, and the No. 2 gear 45 is meshed with the No. 1 gear 44, and the No. 2 gear 45 is separated from the rack 41 and has no contact, and the number of teeth of the No. 2 gear 45 is less than the number of teeth of the No. 1 gear 44, and an open area 2 is penetrated on the No. 1 arc-shaped member 42, and the No. 2 arc-shaped member 43 can be slidably inserted into the open area 2 to complete the closing action. Under normal circumstances, the No. 1 arc-shaped member 42 and the No. 2 arc-shaped member 43 are in a state of being away from each other. When the No. 2 clamping block 39 moves toward the No. 1 clamping block 38, the No. 1 arc-shaped member 42 and the No. 2 arc-shaped member 43 are relatively close to each other and swing to complete the restriction action on the yarn body 4, which is conducive to clamping.

[0065] In the embodiment of the present invention, the guiding mechanism includes a placing table 27 installed on one side of the test table 1 through a bracket, a plug rod 28 is vertically installed on the placing table 27, a bobbin is restricted on the plug rod 28, a yarn body 4 is wound on the bobbin, and a guide seat 29 is installed on one side of the test table 1 above the placing table 27 through a bracket, a first guide wheel 30 is rotatably installed at the bottom of the front end of the guide seat 29, a lifting area 31 is opened through the guide seat 29, a lifting block 32 is slidably engaged in the lifting area 31, a second guide wheel 33 is rotatably installed at the front end of the lifting block 32, and an annular groove is provided on the first guide wheel 30, and the second guide wheel 33 and the first guide wheel 33 are rotatably engaged with each other. 0 cooperates with the annular groove of the swing arm 35, so that the guide wheel No. 1 30 and the guide wheel No. 2 33 can complete the stable restriction of the yarn body 4. The guide wheel No. 1 30 and the guide wheel No. 2 33 are arranged in cooperation to complete the rotation guidance of the yarn body 4, and a limiting spring 34 is installed between the lifting block 32 and the top of the lifting area 31. The limiting spring 34 pushes the lifting block 32 to move toward the guide wheel No. 1 30 in the lifting area 31, and the elastic pressure of the limiting spring 34 is less than the pulling force applied by the swing arm 35, so that when the swing arm 35 pulls the yarn body 4, there will be no breakage problem, and the limiting spring 34 can be replaced with a spring with a different elastic coefficient according to the actual test environment.

[0066] Embodiment 4: A method for detecting tensile strength in a yarn production process, the method specifically comprising the following steps:

[0067] Step 1: First, place the yarn body 4 on the testing mechanism and wait for testing;

[0068] Step 2, then start the synchronization mechanism, and drive the two pressing members 5 to restrict and fix the yarn body 4 through the synchronization mechanism;

[0069] Step 3, the subsequent testing mechanism completes the testing work on the yarn body 4 that has completed the restriction;

[0070] Step 4: Actively restrict and guide the yarn body 4 via the guiding mechanism;

[0071] Step 5: The yarn body 4 introduced by the guiding mechanism is pulled back and forth by the reciprocating mechanism, and is transported to the testing mechanism for restriction, so that the yarn body 4 can be tested repeatedly for many times.

[0072] The present invention provides a tensile force detection device and a detection method for a yarn production process. The specific working principle is as follows: first, a yarn body 4 is placed on a testing mechanism to wait for testing, and then a synchronization mechanism is started, and two pressing members 5 are synchronously driven by the synchronization mechanism to restrict and fix the yarn body 4. The overall operation is convenient, and there is no need to repeatedly disassemble and fix the two ends of the yarn body 4, which reduces the testing process and improves the testing efficiency. Subsequently, the testing mechanism completes the testing work on the restricted yarn body 4, and then the force sensor 8 completes the testing work on the tensile strength of the yarn body 4.

[0073] After a single test is completed, the two clamping members 5 are opened synchronously by the synchronization mechanism to complete the unlocking. Under this path, the gas is ejected through the second gas nozzle 26 through the cooperation of the air chamber 21 and the switching head 23 to actively blow the yarn body 4 remaining in the area of ​​the clamping member 5, which can assist in cleaning and reduce the difficulty of cleaning.

[0074] In addition, the guiding mechanism can actively limit and guide the yarn body 4. In cooperation with the reciprocating mechanism, the reciprocating mechanism can complete the reciprocating pulling of the yarn body 4 introduced by the guiding mechanism, and transport it to the testing mechanism to complete the restriction, thereby reducing the workload of manual repeated installation and disassembly of the yarn body 4, improving the testing efficiency, and facilitating the efficient completion of the testing work. At the same time, multiple repeated tests are completed on the yarn body 4 to ensure the accuracy of the test and avoid accidental conditions affecting the testing accuracy of the yarn body 4. At the same time, the detection device can complete the rapid restriction and fixation of the yarn body 4 and the reciprocating pulling and feeding work through the cooperation of the testing mechanism, the synchronization mechanism, the guiding mechanism and the reciprocating mechanism, thereby effectively reducing the operating difficulty of the operator, facilitating the discovery of the weaknesses of the yarn body 4, and facilitating the subsequent product improvement and upgrading.
